Ball screw kits for Bridgeport milling machines
A ball bearing screw is just that: a screw which runs on ball bearings. The screw and nut have matching helical grooves or races, and the ball bearings recirculate in these races. There is physical contact between the screw and the nut. As the screw or nut rotates, and the rolling balls reach the trailing end of the nut, they are deflected or ...

ballscrew retrofit in a bridgeport mill
On the ball-screw issue -I just bought a cnc/ball-screw converted BP (it will be on-site next week). Acu-rite Millpwr conversion. It allows for manual mode where the servos apply no load. Yes, the table wants to move easily, but nobody seem to have a problem using these in manual mode. Light dragging of a gib can overcome this at the ...
Are ball-screws required for a CNC lathe conversion?
A 5/8 -10 ball screw would be perfect, that way your dial is still accurate. For the carriage, I would not use a ball screw at all. Just use the rack & pinion to drive the carriage, and preload it with an air spring when operating in CNC mode. That way you lose none of the manual functionality of the lathe.
Bridgeport Mill Ball Screw retrofit
Ball-screws may not be much better than normal acme lead-screws if the ball-screw end-play is not zero and if the ends are not pre-loaded correctly. If my lead-screws were too worn I'd opt for a new acme thread and nut combination/set - every time. I can live with even a lot of lead-crew "end-play" or "back-lash" - easily.

anyone using mcmaster's bridgeport ballscrew kit?
I'm kicking around the idea of putting some ballscrews on my 9x42 Bridgeport, possibly for a future cnc conversion but for now, just to fix some worn nuts with no more adjustment. Mcmaster sells a kit for $700 for both screws with nuts and the yolk. Mcmaster's part number is 29995A74. Pretty cheap for a bolt in deal.
Ball screws KGT Trapezoidal thread screws TGT
The term ball screw is used to describe a drive element for the conversion of a rotary motion into an axial motion and vice versa. A ball screw consists of a ball screw shaft, a ball screw nut featuring a ball return and the balls themselves. The balls, which roll between the screw shaft and the nut, offer optimum levels of efficiency (up to 98%).

Ball Screws-????
its practical to convert a mill, although i don't know that exact mill, there are manual mills set up with ball screws.

Enco (Rong Fu RF30) Mill/Drill Conversion
Thanks, Steve. The motor inductance is 6.8 mh per phase, 1.6 ohms resistance and are rated at 3 amps. The holding torque is 280 N cm which converts to about 396 oz in. I bought a 24v, 15 amp power supply specifically for this application, but could buy a different if there would be a significant performance boost.
